Adobe’s Inspire magazine features Photoshop hoss Erik Johansson, his process & his work:
Johansson: I wanted to do something with paper — something more physical, not just a retouch project. Although I obviously use Photoshop quite a bit, I try to do as much as possible in-camera, which makes the illusion look more realistic and makes things easier during post-production.
Nice work by a Photoshop pro. “I try to do as much as possible in-camera” is rather hilarious tho, seeing as there’s probably not a single pixel in the result that hasn’t been retouched at least half a dozen times.
